I To all whomit ma-yconcernt 1 Be it known that-L (h lws' Fxsnsn, of Canton, in the county of: Norfolk and State of Massachusetts, have invented a new and useful lmprovemen't'in Metallic Sleepers for Railways; anti 1 do hereby declare the,fo1.lowing to be ai'ull, clear, and exact description ofth'e same, rem-choc beiug'had to the accompanying drawing making a part of this specification, in which- Figure MS a sectional elevation of the sleeper-box, wooden block, and rail; and v Figure ifis -a plan .view of the-same, with one rail and one of the covering-plates;removed.

. This intention consists in the arrangement of a' hol--' iow metallic tie,'bo.cs' castinside the same near each end, wooden blocks placed .on' rubber cushions in the boxes, with theirfibersruuning vertically for the pur pose-ot"s\1staiuing'therails on slightly-elastic and not easil'ybrokeu"supports; and covering-plates, as herehmfter-more fully set forth.

Referring to the drawinga'is the liollowgiroutie; b, the boxes, cast"iu side the same, near its ends;

c, groores'ruuning crosswise of the upper surface of the tie and of the boxes 1:;

ll, the 'woodell btocks placed on rubbc'r cushion 71-, in

the 'boxes b, wit-h ;their fibcrs running ycrtically, thc uppcuends of said blocks being furrowcd to correspond with the grooves act the tie,-s o that there may be con-- tinuons eha-nucls running through both block and tie,

- the wood projecting up, however, snificieutly ,far 1 to make the bottoms of the block-grooves enough higher than the bottom ofthe tie-grooves to support the rails clear of the tie; entirely upon the blocks, the latter] -also formingbeariugs fln' the sides of thebascs ofthe over the bases of the rails and the tops 'of'those partsdown to [the tics and to protect the blocks.- -'lhe litt-v tcr, being set up endwise, last longer than as though they were laid on their'sideg audas they alou'e sus tain the :railsand are themselves sustainedup'outhe Tubbcr cushions 11-, this combination of 'wood and rub berforms an elasticsupport and one not easily bro: ken. Having thus described my invention,

Whatlclahnas nengand desire to secure by Letters Patent, is-

The arran emcnt of the roored. tie a boxes b'- B 7 7 grooved blocks (1, cushions ligand covering-plates f,'hr .thc inannerlandtor thep n'pose specified.
